3. INSTALLATION AND CONNECTION
3.1 Installation illustration
Installation items:
The factory only provides the main unit and the water unit; the other items in the illustration are
necessary spare parts for the water system, that provided by users or the installer.
Attention:
Please follow these steps when using for the first time
1.Open valve and charge water.
2.Make sure that the pump and the water-in pipe have been filled with water.
3.Close the valve and start the unit.
ATTN: It is necessary that the water-in pipe is higher than the pool surface.
The schematic diagram is for reference only. Please check the water inlet/outlet label on the heat
pump while plumbing installation.

3. INSTALLATION AND CONNECTION
3.2 Swimming Pool Heat Pumps Location
The unit will perform well in any outdoor location provided that the following three factors are
presented:
1. Fresh Air - 2. Electricity - 3. Pool filter piping
The unit may be installed virtually anywhere outdoors. For indoor pools please consult the
supplier. Unlike a gas heater, it has no draft or pilot light problem in a windy area.
DO NOT place the unit in an enclosed area with a limited air volume, where the units discharge
air will be re-circulated.
DO NOT place the unit to shrubs which can block air inlet. These locations deny the unit of a
continuous source of fresh air which reduces it efficiency and may prevent adequate heat delivery.
Air inlet
Air outlet
3.3 How Close To Your Pool?
Normally, the pool heat pump is installed within 7.5 metres of the pool. The longer the distance
from the pool, the greater the heat loss from the piping. For the most part, the piping is buried.
Therefore, the heat loss is minimal for runs of up to15 meters (15 meters to and from the pump =
30 meters total), unless the ground is wet or the water table is high. A very rough estimate of heat
loss per 30 meters is 0.6 kW-hour,(2000BTU) for every 5℃difference in temperature between
the pool water and the ground surrounding the pipe, which translates to about 3% to 5% increase
in run time.
3.4 Swimming Pool Heat Pumps Plumbing
The Swimming Pool Heat Pumps exclusive rated flow titanium heat exchanger requires no special

3. INSTALLATION AND CONNECTION
plumbing arrangements except bypass (please set the flow rate according to the nameplate). The
water pressure drop is less than 10kPa at max. Flow rate. Since there is no residual heat or flame
Temperatures. The unit does not need copper heat sink piping. PVC pipe can be run straight into
the unit.
Location: Connect the unit in the pool pump discharge (return) line downstream of all filter and
pool pumps, and upstream of any chlorinators, ozonators or chemical pumps.
Standard model have slip glue fittings which accept 32mm or 50 mm PVC pipe for connection to
the pool or spa filtration piping. By using a 50 NB to 40NB you can plumb 40NB
Give serious consideration to adding a quick coupler fitting at the unit inlet and outlet to allow
easy draining of unit for winterizing and to provide easier access should servicing be required.
Condensation: Since the Heat pump cools down the air about 4 -5, water may condense on the fins
of the horseshoe shaped evaporator. If the relative humidity is very high, this could be as much as
several litres an hour. The water will run down the fins into the base pan and drain out through the
barbed plastic condensation drain fitting on the side of the base pan. This fitting is designed to
accept 20mm clear vinyl tubing which can be pushed on by hand and run to a suitable drain. It is
easy to mistake the condensation for a water leak inside the unit.
NB: A quick way to verify that the water is condensation is to shut off the unit and keep the pool
pump running. If the water stops running out of the base pan, it is condensation. AN EVEN
QUICKER WAY IS to TEST THE DRAIN WATER FOR CHLORINE - if the is no chlorine
present, then it's condensation.
3.5 Swimming Pool Heat Pumps Electrical Wiring
NOTE: Although the unit heat exchanger is electrically isolated from the rest of the unit, it simply
prevents the flow of electricity to or from the pool water. Grounding the unit is still required to
protect you against short circuits inside the unit. Bonding is also required.
The unit has a separate molded-in junction box with a standard electrical conduit nipple already in
place. Just remove the screws and the front panel, feed your supply lines in through the conduit
nipple and wire-nut the electric supply wires to the three connections already in the junction box
(four connections if three phase). To complete electrical hookup, connect Heat Pump by electrical
conduit, UF cable or other suitable means as specified (as permitted by local electrical authorities)
to a dedicated AC power supply branch circuit equipped with the proper circuit breaker,
disconnect or time delay fuse protection.
Disconnect - A disconnect means (circuit breaker, fused or un-fused switch) should be located

3. INSTALLATION AND CONNECTION
within sight of and readily accessible from the unit. This is common practice on commercial and
residential air conditioners and heat pumps. It prevents remotely-energizing unattended equipment
and permits turning off power at the unit while the unit is being serviced.
3.6 Initial startup of the Unit
NOTE- In order for the unit to heat the pool or spa, the filter pump must be running to circulate
water through the heat exchanger.
Start up Procedure - After installation is completed, you should follow these steps:
1. Turn on your filter pump. Check for water leaks and verify flow to and from the pool.
2. Turn on the electrical power supply to the unit, then press the key ON/OFF of wire controller. It
should start in several seconds.
3. After running a few minutes make sure the air leaving the top(side) of the unit is cooler
(Between 5-10℃)
4. During the operation of the unit, if the filter pump turns off, the unit should also turn off
automatically.
5. Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is
reached. When the water-in temperature reaches this setting, the unit will slow down for a period
of time, if the temperature is maintained for 45 minutes the unit will turn off. The unit will now
automatically restart (as long as your pool pump is running) when the pool temperature drops
more than 0.2 below set temperature.
Time Delay- The unit is equipped with a 3minute built-in solid state restart delay included to
protect control circuit components and to eliminate restart cycling and contactor chatter. This time
delay will automatically restart the unit approximately 3 minutes after each control circuit
interruption. Even a brief power interruption will activate the solid state 3minute restart delay and
prevent the unit from starting until the 5minute countdown is completed.
